Be itv known that I, dor-IN C. MCKALLIP, a citizen of the United States, residing at Houston7 in the county of Harris and State of Texas, have invented certain new and useful Improvements in Sealed Joints for luquid Receptacles7 of'which the following is a specification.

The present invention relates to improvements in liquid receptacles and more particularly to glass tanks for gasoline. 'lhe main object of the invention is to provide effective, sealed joints between the glasscylinder and the metallic ends usually employed for vessels ofthis class. Suchvessels are especially well suited for garages or gasoline service stations where gasoline 1s sold to consumers7 the glass cylinders being desirable for observing the amount of gasoline taken out of the tank.

In the accompanyingdrawing one embodiment ofA the invention is illustrated as applied to a twin tank for gasoline service stations. y y

The figure is a verticall sectional view of a pair of measuring vessels showing the detail construction of the device.

Mounted upon the floor above a gasoline tank is a base or stand 2l to the upper oxtremity'of which is bolted or otherwise connected a cross frame 22. Mounted upon the oppositely extending lateral arms of this frame are the annular base plates23 for the measuring vessels. The plates 23 may be formed integral with the arms of the frame 22 or if preferred may be otherwise connected thereto. Y The yplates 23 are preferably cupped centrally attheir junction with the arms of the frame 22 and communicating with the cupped portions of the said plates are pipes 24 and 25 respectively, connected at their inner extremities to opposite lateral ports of the body 26 of a four-way valve 27. The valve body 26 is rested upon the upper end of the stand 2l and communicating with the lowermost port of the said valve body is a pipe 28 from the tank. Leading from the uppermost port of the valve body 26 is a discharge pipe 29 upon the upper end of which is threaded an annular plate 30. Seating against this plate is a screen 31 extending over the discharge pipe 29 and enclosing the said screen is a cap 32 detachably connected to the said plate by bolts or other suitable fastening devices. Communicating with the cap 32 is a discharge hose 33 equipped with a suitable shut-off valve and delivery spout of conventional design.

The base plates 23 for the measuring vessels are formed upon the'upper sides thereof with annular channels 35 and the outer walls yof vthe said channels are provided with circumferential flanges 36. Seated in the channels of the said plates are complemental upstanding measuring vessels 37 and 38 snugly engaging at their lower extremities against the outer walls of the said channels and resting upon suitable packing gaskets 39 arranged within the channels. The measuring vessels 37 and 38 are preferably transparent and are therefore desirably formed of glass. The inner walls of the channels 35 in the base plates 23 are at their upper margins formed with annular undercut grooves 40 and seated in these vgrooves t0 engage the inner faces of the measuring vessels are packing rings or gaskets 41 of felt or other approved material. These packing rings thus seal the channels 35 and communicating with the said channels are supply pipes 42 through which water is introduced into the said channels. f The packing rings thus become saturated with the water and consequently provide sealed joints between the measuring vessels 37 and 38 and the base plates 23 impervious to thev gasoline introduced into the said measuring vessels. The tendency toward leakage of the gasoline from the measuring vessels at the base plates is thus effectually overcome.

' Closing the upper extremities of rthe measuring vessels are cap plates 43 between which `and the upper edges of the said vessels are preferably interposed packing gaskets 44. The plates 43 are formed with peripheral flanges 45 and extending between the said flanges and the flanges 36 of the base plates 23 are a plurality of connecting rods 46, four of the rods being preferably employed in connection with each measuring vessel and arranged at quadrantly spaced points thereabout. The rods 46 are, at their lower extremities, provided with suitable heads to engage the flanges of the base plates 23 and at their upper extremities are loosely fitted through the flanges 45 of the plates 43 and equipped with nuts adjustable for clamping the measuring vessels 37 and 38 tightly between the said plates. Entering through the cap plates. 43 of the measuring vessels is a pipe 47 in which is arranged a branch coupling thevrise of the gasoline within the ineasuring vessels, these valves will be automatically closed.

Having thus described 'the invention, what is claimed as new is:

l. A vsealed joint for liquid receptacles comprising a base having al continuous groove and a gasket at the bottom thereof, anopen ended vessel engaging with its end f edge in said groove, the edge of said vessel being seated upon said gasket and a packing Vring between the side of said groove and said vessel, said packing ring. being soaked with a liquid having no aflinity to the liquid for which the receptacle is intended.

2. A sealed joint for liquid receptacles comprising a base havingan annular groove and a gasket at the bottom thereof, an open ended cylindrical vessel engaging with its end edge in said groove and the edge of said vessel being seated upon said gasket, a packing ring between the sides of said groove and said vesselfsaid packing ring being' soaked in a liquid having no affinity to the liquid for which the receptacle is intended.

3. A sealed joint for liquid receptacles comprising a base having an annular groove and a gasket at the bottom thereof, an open ended cylindrical glass vessel engaging with its end edge in said groove and the edge of said vessel being seated upon said gasket, a packing ring between the sides of said The valves 5l and 52. are preferably formed of cork so that uponv groove and said vessel, said packing ring being soaked in a liquid having no affinity to lthe liquid 'for which the Ireceptacle is inannular grooveand a gasket at the bottom thereof, yan open ended cylindrical `vglass vessel engaging with its lend edge in said groove and the edge of said vesselbeing seated upon said gasket, a packing ring between the-sides of said groove and said vessel, said packing ring being soaked in a liquid' havin-g lno aflinity ,to the said liquid fuel.

A sealed joint-for receptacles for liquid fuel comprising a base havingvan annular groove and a gasket at the bottom thereof, an open ended cylindrical glass'vessel engagino" with its end edge in .said groove and the edge of saidvessel being seated upon said gasket, a packing ring between the sides of said groove :and said vessel, and means for soaking said packing ring with a liquid having no affinity to said liquid fuel.

A -sealed joint for a receptacle for gasoline comprising a base having an an nular groove rand a gasketvat the bottom thereof, an open; ended cylindrical `glass vessel engaging with its edge insaid groove, the edgev of said vessely being seated upon said gasket, a packing `ring between the sides of said vgroove and said vessel, and means for soaking said packingy rring with water.

't'. ln a measuring Idevice for gasoline, comprising base plates having annular grooves and gaskets at the bottoni thereof, open ended cylindrical glass vessels-engaging with their end edges insaid grooves, the edges of said vessels being seated upon said gaskets, packing rings between the sides of said grooves and said vessels, and means for soaking said packing rings with wat-er.

In testimony whereof I affix myV signature.
